Hello, Paul... Both areas are good. Middletown is more developed than Townsend and has more shopping and restaurants in closer proximity to its neigbhorhoods. Townsend is still a little more rural. Both are in the Appoquinimink School District. Go to my website: http://www.yourdelawarerealestate.com/
and click on the community and school links which will give you more detailed information.
